7105.10.00.11 - 80 mesh or finer

This HTS classification covers dust and powder derived from natural diamonds that are specifically processed to be 80 mesh or finer. This means the particles are very small, with a size equivalent to or smaller than 80 openings per linear inch. Such fine diamond powder is typically used in specialized industrial applications, including precision polishing, lapping, and as a component in advanced cutting tools and abrasives due to its extreme hardness and fine particle size.

This category is distinguished from its sibling, HTS 7105.10.00.15, by the strict mesh size requirement. While both classifications pertain to natural diamond dust and powder, the .11 designation exclusively applies to material that has undergone processing to achieve a fineness of 80 mesh or finer. The .15 category, conversely, encompasses all other natural diamond dust and powder that does not meet this specific particle size criterion, suggesting a coarser or less uniformly processed material.

As a leaf node within the HTS structure, this category does not have further subcategories. Therefore, classification within 7105.10.00.11 is determined solely by the material being natural diamond dust or powder and its particle size meeting the 80 mesh or finer specification. Importers must ensure accurate testing and documentation to confirm the particle size meets this precise requirement for correct classification.
